An early lesson was well underway as Jenny entered the indoor swimming pool. About fifteen senior girls who volunteered for an extra class breaststroked in tandem through the pool, diving their head in and out. The hall even had a 25 feet diving platform.
Mr Patrickson, her ripped gym teacher, noticed Jenny before she did. "Hey", he shouted, stepped around the pool and approached her. "In here it's swimwear only", he warned as he stopped in front of her. "Leave now". But Jenny just gave the man her sweetest smile and playfully bended her head while coiling a strand of her hair around her finger.
"You're right, Mr. Patrickson", she said. "I should be dressed properly". Two seconds later, on the spot where the teacher once stood now lay a sequined silver bikini top along with a matching glittering bikini brief. Holding her satisfied smile, Jenny picked up her former tutor and admired her sheer godlike power.
"I wish I had these on", she demanded, and she instantly wore nothing but the sparkling garments. The other girls, of course, hadn't witnessed anything at all. They kept on rushing through the pool, and they also really didn't seem to care as Jenny hopped into the water. Still underwater, she saw the girl's blurred legs paddle above her and came up with an idea that was more crazy than any she had so far. Testing the real extend of her power, Jenny surfaced and made her wish.
"I wish that every girl and woman can turn into a mermaid anytime she wants". And just like that, all the girls in the pool changed. Their legs merged together, lengthened, became scaly and adopted various colors, like blue, green, pink, purple, silver and gold. Instead of feet they now had split fins at the end of their tails, which waved through the water like those of dolphins. Swimming with fourfold speed than before, the class seemed to enjoy their exercise more by staying more underwater than on the surface, for they obviously had acquired the ability to breath there. Jenny looked down at herself and wanted to be mermaid, too. It felt funny when her legs transformed into a fishtail of the same sequined color as her bikini. It was a childhood fantasy come true. Floating through the water was such an amusement incomparable to anything she did prior. Even after fifteen minutes under the surface she suffered no suffocation, breathing water like air; water that was almost unresisting to her. After a long while of splashing and paddling, Jenny pressed herself out from the pool edge and willed back her human form. Standing on two slender legs again, the magical girl marveled about the apparently endless dimensions of her power. With just a thought and a few words she could alter the universe in any way she could possibly imagine. She almost couldn't choose what to do next.
